Not knowing how far you plan on shooting (practicing or hunting ) its hard to give proper advice. If only shooting out to 40 yds., the three pin sight is probably the best option. You probably won't have time to move your pin while hunting, plus it's extra movement you don't need when trying to beat the vision of a deer. The pin size also depends on shooting distance. Past 40 yds., the .029 pins start to cover too much of your target/bullseye, so .019 pins would be my choice.
